Description

20 25 7907641-o i bromsblockets fästorgan och vilar mot en låsbult, utgör fästorgan för bromsblocket. 7907641-o in the fastening means of the brake block and resting against a locking bolt, constitute fastening means for the brake block.

Uppfinningen beskrives närmare under hänvisning till bifogade figurer. Fig 1 visar ett snitt genom en bromsblockshållare, fig 2, 3 och H visar snitt som anges av A-A, B-B och C-C i fig 1.The invention is described in more detail with reference to the accompanying figures. Fig. 1 shows a section through a brake block holder, Figs. 2, 3 and H show sections indicated by A-A, B-B and C-C in Fig. 1.

I figurerna betecknar 1 konturen av ett järnvägshjul. Bromsblockshållaren 2 är sammansatt av två sidostycken 3, ett lagerrör U, två förbindelseplâ- tar 5 och stoppklackar 6. En bladfjäder 7 är vid sin ena ände svängbart lagrad kring en tapp 8 1 hållarens 2 ena yttre del. Ringen 9 fixerar blad- fjädern 7 i sidled. Vid sin andra ände är bladfjädern fixerad med en låsbult 10. Hållaren 2 är avpassad för två bromsblock 11. Dessa är försedda med två styrklackar 12 som skjuter in mellan sidostyckena 3. Vidare är de utformade med en infästningsanordning 13 som också skjuter in mellan sidostyckena 3.In the figures, 1 denotes the contour of a railway wheel. The brake block holder 2 is composed of two side pieces 3, a bearing tube U, two connecting plates 5 and stop lugs 6. A leaf spring 7 is pivotally mounted at one end around a pin 8 in one outer part of the holder 2. The ring 9 fixes the leaf spring 7 laterally. At its other end, the leaf spring is fixed with a locking bolt 10. The holder 2 is adapted for two brake blocks 11. These are provided with two guide lugs 12 which project between the side pieces 3. Furthermore, they are formed with a fastening device 13 which also projects between the side pieces 3. .

I denna ínfästningsanordning finnes en öppning 1Ä genom vilken bladfjädern 7 passerar. Bromsblockens 11 infästningsanordningar 13 befinner sig mellan stoppklackarna 6 och begränsar blockens 11 tangentiella rörelse inom hålla- ren 2. Bromskraften överföres från blocken 11 genom friktionen mellan broms- blocken 11 och sidostyckena 3. Den kraft som eventuellt ej överföras genom friktion upptages av stoppklackarna 6.In this fastening device there is an opening 1Ä through which the leaf spring 7 passes. The fastening devices 13 of the brake blocks 11 are located between the stop lugs 6 and limit the tangential movement of the blocks 11 within the holder 2. The braking force is transmitted from the blocks 11 by the friction between the brake blocks 11 and the side pieces 3. The force which may not be transmitted by friction is absorbed by the stop lugs 6.

Utbyte av bromsblock genomföres på följande sätt. Låsbulten 10 borttages och fjädern 7 med blocken 6 svänges ut mot hjulet 1 så att infästnings- anordningen 13 går fri från stoppklacken 6, varefter förslitna block av- lägsnas. Ett första block skjutes upp längs fjädern 7. Detta kan låsas med en lâspinne som insättes i hålet 15 medan ett andra block 11 skjutes upp på fjädern 7. Denna svänges nu tillbaka och fixeras med låsbulten 10.Replacement of brake pads is performed as follows. The locking bolt 10 is removed and the spring 7 with the blocks 6 is swung out towards the wheel 1 so that the fastening device 13 moves free from the stop lug 6, after which worn blocks are removed. A first block is pushed up along the spring 7. This can be locked with a locking pin which is inserted into the hole 15 while a second block 11 is pushed up on the spring 7. This is now pivoted back and fixed with the locking bolt 10.
